The term WHISPERED STAGE LINE is composed of two words, ASIDE and WHISPERED. ASIDE is a five-letter word meaning 'to one side; out of the way.' WHISPERED is an eight-letter word meaning 'spoken in a low voice.' Together, the term WHISPERED STAGE LINE refers to a theatrical device in which actors speak their lines in a low voice, as if they are speaking to themselves or to another character offstage. This technique is used to create a sense of intimacy and realism in a performance.
